Problems solved by technology

[0003] The performance parameters of the current trackless bus are not good. For example, some manufacturers use a single-tire bus. Each tire can realize the steering function independently, but the carrying capacity is insufficient, especially when the body size of the bus is long. The carrying capacity is limited, the load-bearing capacity of the axles and tires can only meet the weight of the car body, and it is impossible to free up too much weight to meet the passenger demand, resulting in the failure to meet the vehicle configuration requirements; although some manufacturers adopt twin tires (left and right arrangement structure) The passenger car with two single tires) solves the load-carrying problem, but the wheels of its twin tires do not have the steering function, resulting in the lack of flexibility of the car body during the steering process, which is not suitable for low-floor buses. The inner tires will have strong friction with the ground, and the degree of wear and tear will be greater. The passenger car with twin tires will also narrow the aisle of the car body, and the size of the car body is not good, which will affect the passenger capacity.

Embodiment 1

[0038] The first printed track train comprises a body 1 made up of multiple carriages 2, and wheels are arranged below the carriages 2. In this embodiment, a steering drive module 3 is connected between the carriages 2 and the carriages 2. The steering drive module 3 includes Wheel body one 301, wheel body two 302, wheel body three 303 and wheel body four 304, the wheel body one 301 and the wheel body two 302 are located in front of the wheel body three 303 and the wheel body four 304, and Wheel body one 301, wheel body two 302, wheel body three 303 and wheel body four 304 are connected to the base respectively, and a steering system is provided on the base, and the steering system is connected to wheel body one 301, wheel body two 302, The third wheel body 303 and the fourth wheel body 304 are connected by a support.

[0039] The first wheel body 301 and the third wheel body 303 are located on the same side of the vehicle body, and the second wheel body 302 and the fourth whe...

Embodiment 2

[0053] The second track train is the same as Embodiment 1, and it includes a steering drive module 3. The steering drive module 3 has four wheel bodies, which are respectively wheel body one 301, wheel body two 302, wheel body three 303, wheel body three, and wheel body three. Body 4 304, the positional relationship of each wheel body is the same as that in Embodiment 1, and will not be repeated here.

[0054] Please combine image 3 , wherein, a shaft is connected between the first wheel body 301 and the second wheel body 302, a differential is connected to the middle of the shaft, the differential is connected to a motor, and the third wheel body 303 is connected to the A shaft is also connected between the four wheels 304, and a differential is also connected to the middle of the shaft. The differential is also connected to a motor, and the front and rear differentials and the motor are respectively installed on the base to form a On the whole, the motor and the controller...

Abstract

The invention discloses a steering drive module and a corresponding vehicle, and relates to the technical field of trolleybuses. The steering drive module is provided with four wheel bodies, a motor provides driving force for the wheel bodies in a centralized or decentralized mode, a steering controller utilizes a hydraulic actuator to execute a steering instruction, driving and steering are integrated, and thus the vehicle achieves flexible steering of the wheel bodies when meeting the bearing requirement. The invention further discloses a trolleybus provided with the steering drive module, and the trolleybus determines the wheel path and achieves the function of tracking by recognizing ground marks or the direction of front steering wheels.

Description

technical field [0001] The present invention relates to the technical field of trackless buses, in particular to a steering drive module, which is used to realize the integrated control of steering and driving, and also relates to a track train, which adopts the steering drive module to carry out integrated control of driving and steering. , and can also realize the functions of tracking and printing. Background technique [0002] In order to alleviate the problem of urban traffic congestion, trackless buses have gradually entered the public's field of vision. With the continuous development of technology, trackless buses have begun to change from gas to electric to improve environmental performance. [0003] The performance parameters of the current trackless bus are not good. For example, some manufacturers use a single-tire bus, and each tire can realize the steering function independently, but the carrying capacity is insufficient, especially when the body size of the bu...
